Learn how highly accurate long-read sequencing from the Sequel IIe Systems delivers data you can trust for advanced biological insights across a range of applications.
Learn how Single Molecule, Real-Time (SMRT) Sequencing and the Sequel IIe System and will accelerate your research by delivering highly accurate long reads to provide the most comprehensive view of genomes, transcriptomes and epigenomes.
PacBio Sequencing is characterized by very long sequence reads (averaging > 10,000 bases), lack of GC-bias, and high consensus accuracy. These features have allowed the method to provide a new gold standard in de novo genome assemblies, producing highly contiguous (contig N50 > 1 Mb) and accurate (> QV 50) genome assemblies. We will briefly describe the technology and then highlight the full workflow, from sample preparation through sequencing to data analysis, on examples of insect genome assemblies, and illustrate the difference these high-quality genomes represent with regard to biological insights, compared to fragmented draft assemblies generated by short-read sequencing.
In this Webinar, we will give an introduction to Pacific Biosciences’ single molecule, real-time (SMRT) sequencing. After showing how the system works, we will discuss the main features of the technology with an emphasis on the difference between systematic error and random error and how SMRT sequencing produces better consensus accuracy than other systems. Following this, we will discuss several ground-breaking discoveries in medical science that were made possible by the longs reads and high accuracy of SMRT Sequencing.
SMRT Sequencing is a DNA sequencing technology characterized by long read lengths and high consensus accuracy, regardless of the sequence complexity or GC content of the DNA sample. These characteristics can be harnessed to address medically relevant genes, mRNA transcripts, and other genomic features that are otherwise difficult or impossible to resolve. I will describe examples for such new clinical research in diverse areas, including full-length gene sequencing with allelic haplotype phasing, gene/pseudogene discrimination, sequencing extreme DNA contexts, high-resolution pharmacogenomics, biomarker discovery, structural variant resolution, full-length mRNA isoform cataloging, and direct methylation detection.
In this AGBT 2017 talk, PacBio CSO Jonas Korlach provided a technology roadmap for the Sequel System, including plans the continue performance and throughput increases through early 2019. Per SMRT Cell throughput of the Sequel System is expected to double this year and again next year. Together with a new higher-capacity SMRT Cell expected to be released by the end of 2018, these improvements result in a ~30-fold increase or ~150 Gb / SMRT Cell allowing a real $1000 real de novo human genome assembly. Also discussed: Additional application protocol improvements, new chemistry and software updates, and a look at…
PacBio sequencing has been recognized as the gold-standard in microbial sequencing due to simultaneously providing long sequence reads (genome contiguity), high consensus accuracy (genome accuracy), minimal sequence bias (genome completeness), and methylation detection (bacterial epigenome). In his talk Jonas Korlach, highlights new advances and updates on applying PacBio sequencing in microbiology, including multiplexed microbial sequencing on the Sequel System and full-length bacterial RNA sequencing. In the second part of his talk, he covers how the generation of high-accuracy, single-molecule consensus reads, through a process called circular consensus sequencing – a capability unique to PacBio sequencing technology – can be leveraged…
In this webinar, Lori Aro and Cheryl Heiner of PacBio describe how high-throughput amplicon sequencing using Single Molecule, Real-Time (SMRT) Sequencing and the Sequel System allows for the easy and cost-effective generation of high-fidelity, long reads from amplicons ranging in size from several hundred base pairs to 20 kb. Topics covered include the latest advances in SMRT Sequencing performance for detection of all variant types even in difficult to sequence regions of the genome, multiplexing options to increase throughput and improve efficiency, and examples of amplicon sequencing of clinically relevant targets.
In this webinar, Jonas Korlach, Chief Scientific Officer, PacBio provides an overview of the features and the advantages of the new Sequel II System. Kiran Garimella, Senior Computational Scientist, Broad Institute of MIT and Harvard University, describes his work sequencing humans with HiFi reads enabling discovery of structural variants undetectable in short reads. Luke Tallon, Scientific Director, Genomics Resource Center, Institute for Genome Sciences, University of Maryland School of Medicine, covers the GRC’s work on bacterial multiplexing, 16S microbiome profiling, and shotgun metagenomics. Finally, Shane McCarthy, Senior Research Associate, University of Cambridge, focuses on the scaling and affordability of high-quality…
To start Day 1 of the PacBio User Group Meeting, Jonas Korlach, PacBio CSO, provides an update on the latest releases and performance metrics for the Sequel II System. The longest reads generated on this system with the SMRT Cell 8M now go beyond 175,000 bases, while maintaining extremely high accuracy. HiFi mode, for example, uses circular consensus sequencing to achieve accuracy of Q40 or even Q50.
In this webinar, Jenny Ekholm and Paul Kotturi provide an overview of the PacBio No-Amp targeted sequencing application and its uses for targeting hard-to-amplify genes. This approach couples CRISPR-Cas9 with Single Molecule, Real Time (SMRT) Sequencing to enrich targets, without the need for PCR amplification, and generate complete sequence information with base-level resolution.
In this webinar, Kristin Mars, Sequencing Specialist, PacBio, presents an introduction to PacBio’s technology and its applications followed by a panel discussion among sequencing experts. The panel discussion addresses such things as what long reads are and how are they useful, what differentiates PacBio long-read sequencing from other technologies, and the applications PacBio offers and how they can benefit scientific research.
The release of the PacBio Sequel II System in 2019 brought dramatic throughput improvements and protocols for producing a new data type, highly accurate long reads or HiFi reads. PacBio is the only sequencing technology to offer highly accurate long reads (HiFi reads) that provide Sanger-quality accuracy (>99%) with the read lengths needed for assembly of complex genomes. The long length and high accuracy of HiFi reads makes them the ideal starting point for many applications, and one area of major interest is genome assembly. HiFi assembly is faster, cheaper, more accurate, and easier to phase than standard long-read assembly.…
In this SMRT Leiden 2020 Online Virtual Event presentation Pedro Oliveira of Mount Sinai shares his research on Clostridioides – a leading cause of nosocomial-acquired diarrhea and colitis across the developed world. In this study, Oliveira and coworkers performed the first comprehensive DNA methylome analysis of 36 human C. difficile isolates from a hospital setting using SMRT Sequencing and comparative epigenomics.
PacBio SMRT Sequencing has the unique ability to directly detect base modifications in addition to the nucleotide sequence of DNA. Because eukaryotes use base modifications to regulate gene expression, the absence or presence of epigenetic events relative to the location of genes is critical to elucidate the function of the modification. Therefore an integrated approach that combines multiple omic-scale assays is necessary to study complex organisms. Here, we present an integrated analysis of three sequencing experiments: 1) DNA sequencing, 2) base-modification detection, and 3) Iso-seq analysis, in Neurospora crassa, a filamentous fungus that has been used to make many landmark…
